Isolated tetrazoospermia
My husband has been diagnosed with having very poor sperm morphology. His best sample has been 1% normal forms, but his count and motility is within range. Is ICSI the best option for isolated morphology problems? What would be the potential cause of this problem, and why would the motility and count not be affected?

The cause of isolated teratozoospermia is not known but there may be some genetic reason. ICSI is recommended as it improves the fertilisation rate with poor morphology and the Embryologist can look carefully at the sperm and only select the best shape for injection.
